摘要： Embodiments of the present disclosure provide an earthing switch, associated manufacturing method and switchgear. The earthing switch comprises a plurality of fixed contacts for a plurality of phases of the switchgear and each comprising a pair of contact fingers; and a plurality of movable contacts adapted to be driven to rotate between an open position and a closed position and each comprising a supporting section and a tubular coupling section attached to the supporting section, the supporting section and the tubular coupling section made of different materials, wherein the tubular coupling section is clamped between the pair of contact fingers in the closed position to close a ground loop and is detached from the pair of contact fingers in the open position to open the ground loop. With the movable contact comprising two sections made of different materials, the weight and the cost of the movable contact are allowed to be significantly reduced without affecting the performance of the earthing switch. Furthermore, the movable contact can move at a higher speed under the same driving power, thereby further improving the safety performance of the earthing switch.

摘要： A switchgear (200) and an apparatus for measuring temperature of the switchgear (200). The switchgear (200) comprises a busbar compartment (202) and a circuit breaker compartment (203), and the apparatus comprises at least one sensor (101) arranged at a busbar (201) in the busbar compartment (202) and adapted to sense a temperature of at least one predetermined position of the busbar (201); a transmission module (102) coupled to the at least one sensor (101) and adapted to transmit data representing the temperature of the at least one predetermined position; and a power module (103) adapted to power the at least one sensor (101) and the transmission module (102), wherein at least one of the transmission module (102) and the power module (103) is detachably arranged at an interface (204) between the circuit breaker compartment (203) and the busbar compartment (202). With the transmission module (102) and/or the power module (103) detachably arranged at the interface (204) between the circuit breaker compartment (203) and the busbar compartment (202), the transmission module (102) and/or the power module (103) may be separately replaced. In this way, replacement efficiency is significantly improved and maintenance costs are reduced. Furthermore, the interface (204) where the transmission module (102) and/or the power module (103) is arranged allows the replacement of the transmission module (102) and/or the power module (103) without powering off the entire busbar (201), which improves reliability of the switchgear (200).

摘要： An apparatus (100) for releasing arc pressure of a switchgear and a switchgear system. The apparatus (100) comprises a foldable member (10) comprising a first plate (102) and a second plate (104) arranged on a plane structure (122) of the switchgear and spaced apart from each other and a plurality of plates coupled in series between the first plate (102) and the second plate (104), wherein each of the plurality of plates is rotatable with respect to adjacent plates such that the foldable member (10) is switchable between a folded state and an unfolded state, wherein in the unfolded state, the foldable member (10) together with the plane structure (122) form a duct structure, and wherein the foldable member (10) has a smaller thickness in the folded state than in the unfolded state; and fixing parts (20) each arranged at a joint between two adjacent plates and configured to fix the two adjacent plates when the foldable member (10) is in the unfolded state.

摘要： Embodiments of the present disclosure provide a shutter mechanism for a switchgear. The shutter mechanism comprises a first moveable cover and a second moveable cover arranged between fixed contacts and moveable contacts of a circuit breaker on a withdrawable truck of the switchgear; and a transmission mechanism arranged at least in part below the withdrawable truck and coupled to the first and second moveable covers, the transmission mechanism adapted to be actuated by a movement of the withdrawable truck to drive the first and second moveable covers to move close to each other to a block position to block the fixed contacts when the withdrawable truck moves to a test position, and move away from each other to an unblock position to unblock the fixed contacts when the withdrawable truck moves from the test position to an intermediate position between the test position and a work position. With such an arrangement, the first and second moveable covers cannot be opened by manually operating the transmission mechanism directly or by pushing the covers, improving the safety of the shutter mechanism.

摘要： A switchgear comprises a bypass busbar (101B); at least one main busbar (101A); a disconnector (104A); and a circuit breaker (102A) connected with the at least one main busbar (101A). The disconnector (104A) comprises a blade (1045) which can be driven to three positions, i. e., a first position (P1) for connecting with an outcoming of the circuit breaker (102A), a second position (P2) for connecting with an outcoming of the bypass busbar (101B), and a third position (P0) for disconnection. The bypass busbar (101B), the at least one main busbar (101A), the circuit breaker (102A), and the disconnector (104A) are all arranged within a single panel. Moreover, the blade (1045) is driven by an operation mechanism (106) including a four-bar linkage driving means (1040). The three-position disconnector (104A) is implemented by means of four-bar linkage driving means (1040) and thus all functionalities for a feeder can be achieved within one single panel, which provides a great deal of cost and space savings.
